 * Not sure if this is the correct section to ask this or not:
 * I am trying to create a post for my front page, but when I try to attach images
   of products for illustration purposes, I get the following error message:
 * Fatal error: Call to undefined function get_post_thumbnail_id() in /home/content/
   98/6575898/html/wp-admin/includes/media.php on line 1314
 * The images work fine for individual products, but not when attaching any image
   to a post or new page, regardless of source (desktop, iphoto, media). It has 
   worked in the past, so not sure what is different. I use in conjunction with 
   the SimpleCart 2.1 theme.
 * So far, I have disabled all plugins, but that made no difference. I have re-installed
   WP 3.1.3 as well as Shopp and SimpleCart to no avail.
 * Any help is appreciated.
 * Thanks
